l5, the wall 17 beinghinged at one edge 18 i so as to permit of outwardswinging of the opposite edge thereof'in order to gain access to thecompartment A. The wall 17 is locked in operative position by means oflatches 19 and 20 slidably mounted upon Fig. 10. lA helical compressionspring 21'4 coperates with the member 19 for normally holding the samein operative position, the other latch being held in operative positionby gravity. Exteriorly positioned knobs 22 cooperate with latches 19 and20 for manually moving the same to unlocking position.

One of the lateral -walls 23 of the housing, as clearly shown in Fig. 5,is rigidly secured to the frame 15, the other lateral wall 24 beinghingedly connected with the rear wall 25 of the housing at 26, said rearwall being in turn hingedly connected at 27 with thepiear edge ofwall23, the arrangement being such as to permit of the walls 24 and 25 beingswung around and folded together, as shown in dottedlines in Fig. 5,

so as to permit of ready access to the interior of the device. The wall24 is locked in operative position by means of latches 28 which areslidably mounted upon the inner side of said` wall adjacent the frontedge thereof, as clearly shown in Fig. 10-,said latches being adaptedfor engagement with sockets provided for coperation therewith in theframe 15. Said latches 28 are controlled by a key which may be insertedthrough ap exteriorly opening key hole 29,

.as will be readily understood. The free edge of the front wall 1-7which is bent back to forin the end wall of compartment A is'pi'ovidedwith arearwardly projecting flange 30 which isadapted to overlap withthe front edge ofwall 24, thus making it necessary to first unlock thewall 17 before tlie wail 24 may be swung outwardly. .Cooperating withthe rear wall 25 are also slidably mounted latches 31 vand 32 arrangedupon the inner side thereof, as clearly shown .in Fig. 11, said latchesbeing adapted for engagement with sockets `provided for cooperationtherewith in frame 15 in the same manner as latches 19 20 and 28. Ahelical compression spring 33 coperatcs with the latch 31 for normallyholding the saine in Alo opens into the rearward end of a projectingtube 36 which projects forwardly from said wall, being provided at itsfront end with the usual lenses mounted in an adjustably mounted holder36. Formed in the wall 16 is la, coaxial circular opening 37 behindwhich are mounted the conventional condensing lenses carried in a holder38 mounted upon the inner side of wall 16, as clearly. shown in Fig. 1.Arranged directly behind the lense holder 38 is an arc lam 39 with theupper end of which communicate electric conductor wires 40.'.1 The lamp3') is suspended from a substantially inverted U- shaped verticallyadjustable support 41, said supportbeing held in positions of verticaladjustment yby means 0f thumb screws 42 which are threaded upon studs 43projecting inwardly from Ydepending arms 45. The ends or sides of member41 are provided with elongated slots 46 to afford clearance for thestuds 43, as clearly shown in Fig. 4. The upper ends of arms 45 slidablyengage -with supporting bars 47' formed integral "with frame 15, thearrangement being such as to permit of adjustment of the are lamp towardand from the condensing lenses. Set

screws 48 coperate with the members 45 for locking the samein positionsof adjustment.

" With this arrangement then it will be seen that, through the verticaladjustment afforded the supponting element 41 and through the horizontaadjustment afforded the supporting arms 5, the lamp may be adjustedvertically and horizontally in order to properly position the samerelative with which the same copera The upper wall of the housing of thedevice is cut away as at 49 to afford clearance for the upper end ofthelamp and the su port therefor, a supplemental housing .59 heiligarranged upon the upper end of the main housing for inclosing said endof the lamp and the support therefor. The supplemental housing 50 issecured in position by means of nuts 51 which engage with studs 52projecting upwardly from frame 15, as clearly shown in Figs. 4 and 9.

Arranged in the compartment A is a cir` cular slide-holder 53 which ismounted upon the front end f a shaft 54 rotatably mounted insuitableydearings securedto supporting bars 55 and 56formed integralwith the frame 15, at the front and rear sides thereof,*as clearly shownin they several views. 'lheslide-holder is 'formed' adjacent its peirlphery with a plurality of equally spaced rectangular openings ,57,ove'.` which. the

slides 58, which it is desired to project, are

adapted to be arranged. The slides 58 are Fig. 3, are adapted to engagewith the innerl ends of slides 58 to limit inward movement thereof. Theslide-holder 53 is so mounted that, in the rotation thereof, the slides58 will be successively brought into registration with the projectinglenses in order to effect the projection of the pictures or matter uponsaid slides through the projecting tube 36. 'A

Rotation of the shaft 54 is controlled by a pair of ratchet wheels 461and 62 secured to the front ,and rear ends respectively of .said shaft.Coperating with the ratchet 61, as clearly shown in Figs. 6 and 7, is apawl 63 which is pivoted at 64 to the supportingA bar I55. 'A helicaltension spring 65 coperates with the pawl 63- to normally hold the samein operative relation with4 the ratchet'wheel 61 'in order to preventpositiveorforward rotation of the shaft 54, it being necessary,therefore, with this arrangement in releasing the shaft 54 so `as topermit ofpositive rotation thereof, to rst rock the vpawl 63 toinoperative position. For V.this purpose the pawl 63 is formed withv asubstantiallyI horizontally disposed extension 66 which is adapted forengagement bymechanism hereinafter described in effecting releasingmovement of `pawl 63. Coperating' with the ratchet wheel 62, as clearlyshown -in Figs. 4 and 7, isa pawl 67 hinged `at 68-to a supportingarm.69 projecting upwardly to the lenses i f rom supportingbar 56.l Ahelical tension spring 70 coperates with the pawl 67 to normally holdthe` same in operative relation with said ratchet wheel 62 in order toprevent retrograde rotation of the shaft 54.

Arranged below the shaft 54 is a shaft 71 rotatably mounted in suitablebearingssecured to frame bars 72 and 73 formed integral -with frame 15.Fixed to the'shaft 71 is a gear 74 with which meshes a pinion 75 fixedto a shaft 76 which is mounted in suitable bearings also secured tosupporting bars 72 and 73. The shaft 76 also carries a worm wheel 77which meshes with a worm 78, as clearly shown in Fig.v 4, provided uponthe power shaft 79 of an electric motor 8 said motor and power shaftbeing s itably mounted upon bearings arising front the bottom of thehousing of the machine. .,Conductor wires `81 are shown for coperationwith the motor 80, said wires together with'` the conductor wires 40\which coperate with the lamp 39, bemg united for connection with 'asourceof electrical energy. -With this arrangement it Will be seen thatupon operation of the motor the gear 7a will Vbe rotated. i

Formed in one side of the gear '74, as clearly shown in Fig. 8, is anannular chan- Iiel 82 in'the bottom of which is formed an annular' slot83, the inner and outer parts of the gear which are thus completelysevered from each other` being connected by straps S4. Mounted forsliding adjustment in the slot v1831s a plurality of tappet members 85wir i are adjustably fastened to the gear 7J( by-ineans of 'screws 86and cooperating nuts 87. The inner ends of the tappets 85 are square inorder to prevent relative rotation of the same in the slot 83. The outerend 85 of each tappet is angularly formed for engagement with thee\tension4 G6 of the pawl 63, as clearly shown in Fig. 7,-so that` inthe rotation of gear 74, the pawl G3" will be successively moved toinoperative position by y reason of the successive engagement of theends 88 of the tappets with said extension 66.

Mounted upon the shaft fill, adjacent the l ratchet 61, is a gear orsproeketwheel 8'.)

which is positioned eoplanar with the inner 'or base portions of thetappets 85, as clearly shown in Fig. 8. The arrangement is such that, inthe rotation of the gear 74, the base portions of the tappets 85 willsuccessively engage with the"teeth of member 89 in order.

to effect intermittent rotation thereof and hence of the slide-holdercarried -by the shaft 54, The extension 6G of the pawl (33 is sopositioned relative to the member Si), that said pawl will be moved toreleasingl position vby each tappet extension 88 before the tappetproper engages with said member 89. Also, the parts are soproportionedthat carry oneslide from projecting position and to carryfthe succeedingslide'vin projecting position. Thus, the successive engagen'ient of thetappets with the member 8S) will serve to intermittently move theslide-holder to successively position the slides carried thereby forprojection from the machine. Upon the vjjmssage of a tappct fromengagement xiviththe member 8f) and the extension ($6 of theI pawl (38,the latter will immediately moveto operatij-'e position under the in-.;fiuence of spring (35 so as to preventexcess y'movement of theslide-holder through inyei'ti'a. By spacing the tappets along theslot-83, it is, of course, apjiarent that the `duration of exposure ofthe slides projected un the machine may be governed de- -ed and anynuinber of tappets may be employed, vdepending' upon the length of timeit is desired to expose each slide.

Through the hinged mounting of the front ifall 17, access may be readilygained lturbing any other part of the mechanism.

Access to the interior of the machine for adjustment of the tappets, orfor any other purpose, may' be readily and easily gained by unlocking ofthe walls 24 and 25 and swinging of the same to the dotted line positionshowniin Fig; 5.

With the construction set forth then` it will be seen, that a machine isprovided which, in operation, is entirely automatic, the slides carriedby the slide-holder upon which advertising or other matter may be ai'langed. being successively projected from the machine onto the screenwhich is used in connection with thenulchine.
